setPrompt: command not found in GRASS7-svn

[moovida]

The grass7 command shell doesn't appear to permit to have an own setPrompt.

I use a customized one to have some different information/coloring of the prompt in the case of git and hg repos:

function setPrompt(){
    thedate=`date "+%F %T"`
    if [ -d ./.git ]; then
        GITBRANCH="$NC($GREEN$(awk -F '/' '{ print $NF }' .git/HEAD)$NC"

        if [ $(git diff --exit-code > /dev/null 2>&1; echo $?) -eq 1 ] || [ $(git diff-index --cached --quiet --ignore-submodules HEAD --; echo $?) -eq 1 ]; then
          GITBRANCH="$GITBRANCH [$RED*$NC"
        else
          GITBRANCH="$GITBRANCH [$MAGENTA-$NC"
        fi

        if [ "x$(git status | grep Untracked)" != "x" ]; then
          GITBRANCH="$GITBRANCH$RED+$NC])"
        else
          GITBRANCH="$GITBRANCH$MAGENTA-$NC])"
        fi
        echo -e "\n${GREEN}GIT:${NC} ${GITBRANCH}"
        echo -e "${GREEN}======================================================  $thedate${NC}\n\n\w >>> "            
    elif [ -d ./.hg ]; then
        HGBRANCH="$NC($CYAN$(awk -F '/' '{ print $NF }' .hg/branch)$NC"

        if [ "x`hg status | grep ?`" != "x" ]; then
          HGBRANCH="$HGBRANCH [$RED+$NC])"
        else
          HGBRANCH="$HGBRANCH [$MAGENTA-$NC])"
        fi
        
        echo -e "\n${CYAN}HG:${NC} ${HGBRANCH}"
        echo -e "${CYAN}======================================================  $thedate${NC}\n\n\w >>> "            
    else
        echo -e "${RED}======================================================   $thedate${NC}\n\n\w >>> "            
    fi
}

which leads me to the error in the subject.

While for example in grass64 I have:

GRASS 6.4.0+42329 (gbovest):~ > echo $PROMPT_COMMAND 
'/usr/lib/grass64/etc/prompt.sh'

in grass7 it seems to have changed to:

echo $PROMPT_COMMAND
PS1="$(setPrompt)"
